Mandy finds a BBC for a threesome

Erotic Fiction

Part-2

About a week later I was home and working on a book that I'm trying to write when my mother came in with my phone in her hand. "It's your sister," she said as she handed it to me. "You left this in the bathroom."

A quick aside about my mother. She is in her mid-fifties, attractive in face and figure--a true MILF--and has been happily divorced for about a year. Even though Mandy and I are in our mid- and early-twenties respectively, we still live at home. This is convenient and economical for us, of course, but we both pay a reasonable room-and-board to help her make ends meet, so it works well for her, too. She also likes having us around. The three of us have a great relationship. And in case you're wondering, no, she doesn't know that both of her kids are hypersexual and regularly fuck one another in their childhood bedrooms. Some things are better kept a secret!

Anyway, back to Mandy's call.

"Hey, bro," she said when I answered. "You interested in a three-way with a BBC that I just met?"

"You just met him and you already know he has a BBC?" I replied.

"Well, he's sure as hell black, and I'm making an assumption on his dick based on the size of the rest of him," she answered. "He used to play for some football team."

"Really? Which one?" I asked.

"I don't know," she replied. "I was too busy thinking about him and his naked teammates in the locker room when he told me. And who the hell cares?"

"Good point!" I laughed. "Yeah, I'm in. Mom's home so it can't be here, though."

"It'll be at his place," she said. "And I told him that you're my cuckold fiancé, by the way."

I laughed, and said, "Well, that's a new one but it sounds like it could be fun! Did you happen to ask if he's bi?"

"Not specifically," she said, "but when I mentioned that you were a cuckold, he asked, '

So, does he just watch you getting fucked while he plays with his pecker, or does he get in there and eat your lover's cream-pie and maybe clean up his dick?

' So, that tells me that he's not homophobic, at least. Certainly not like Rodney was."

Another quick aside. Rodney was one of Mandy's lovers, and when she called me into her room to clean him and her up, he was surprised and confused at what was going on. But when I crawled onto the bed and took his wilted dick in my mouth, he shoved me away, jumped off the bed, and shouted, "

I ain't into no queer bullshit!

" and took off as soon as he could pull his pants on. Sucks to be him!... and not in the good way.

So, anyway, a half-hour later I was pulling up in front of a sprawling single-story house in a prime neighborhood. Mandy met me at the door and then introduced me to "Harry" (not his real name for obvious reasons).

If I had not already been bi, I would have skipped right over that and become full-on gay to be with this guy! He was probably six-foot-seven, still had the build of a running back, and was damned good looking! I could see why Mandy assumed he had a BBC. It would have been a cruel trick of nature if it was otherwise.

"This is my hubby-to-be, Donny," she said to Harry. "I let him make love to me, but honestly, he's not very good at it, although he

is

learning. That's why I like him to watch when somebody who knows what they're doing with a stiff cock fucks me." She turned to me, and added, "And you

like

to watch me get fucked by talented lovers, don't you, Donny?"

I swallowed and cast my eyes downward as if I felt humiliated, but in reality, I was aroused as hell. "Yes," I answered meekly.

"And you like to

help

, too, don't you?" she went on.

"Yes," I repeated.

She took Harry's hand, and asked, "Which way to your bedroom?"

The bedroom was huge, and the bed was massive. It had most likely been custom-built for his size.

"You can start by taking our clothes off," Mandy told me.

"Who first?" I asked. I was really hoping she'd say Harry. I'd seen her naked plenty of times, but I couldn't wait to see the body he was hiding under his clothes.

Mandy would have known that, of course, so to build my tease, she naturally said her.

Harry sat on the edge of the bed and watched as I unbuttoned her blouse, slid it off, folded it, and laid it on a dresser. Then I took off her skirt, leaving her in her thong panties and her low-cut bra. I moved behind her and unfastened the bra, sliding it off her shoulders and down her arms, freeing her tits to his gaze.

"Give them a little rub, Donny," she told me. "Get the blood circulating in them."

I reached around her and cupped both of her breasts in my hands. Mandy doesn't have jugs, but over the years, the little-girl martini-glass boobs of her youth had grown into perfect womanly tits. They were large enough to have just a tiny bit of droop so you could feel their wonderful weight when you cupped them, and when squished together, she could give a great titty-fuck. Her nipples were still puffy and pink.

As Harry watched me dutifully massaging her tits, I pressed my hips against her ass-cheeks so she could feel the raging boner in my pants. She responded by pushing back and swiveling her hips. She said to Harry, "Somebody's pecker is all excited about showing off his bride-to-be's naked body to you."

He chuckled, and with a big hand gripping the bulge in his pants, he said, "He ain't the only one! You are one freaking sexy fiancé!" To me, he said, "You have any idea how lucky you are, dude?"

"Oh, I know!" I said while thinking

You have no idea!

She took my hands, slid them down her body to her hips, and told me, "Take my panties off and smell them. I want you to see how aroused I am at the thought of having a new lover."

I slid them down her legs and then held them to my nose and inhaled. I love the smell of my sister's pussy, especially when it's wet with her arousal-juices before it's even been touched. My boner throbbed in my pants and leaked a squirt of pre-cum.

"May I?" Harry asked holding out his hand for the panties. I handed them to him, and with closed eyes, he took a long sniff of their crotch. "Oh, that's nice!" he said. "I'm looking forward to

tasting

that!"

My now-naked sister stepped to the side, pushed me forward, and told me, "Now, take off Harry's clothes."

But he remained sitting and said to Mandy, "You mind if he strips himself, first? I want to see how excited he is to watch his wife-to-be with another man."

That he wanted to see my dick before he even had his clothes off was a bit of a surprise. Was he just adding to Mandy's taunting or was he perhaps bi--or maybe bi-

curious

--and he was as anxious to see my cock as I was to see his? I could only hope!

My shirt and pants were off in seconds, and when I pushed down my snug boxers and my boner sprang straight out, he blinked in apparent surprise. Being a

cuckold fiancé

, he was probably expecting to see a stiff-but-unimpressive wiener, but my dick is above average in length and thickness with its big, well-defined knob being its most noteworthy feature. He looked at Mandy, and said, "Well, not too much to complain about there."

She replied, "As the old saying goes,

it's not the size of the pencil, but how you write with it that counts

. And he needs tutoring in that regard." That wasn't true, of course, but it fit with the dominated-cuckold role I was playing. Regardless, I was looking forward to him

showing me how it was done

! I was sure that Mandy was, too. She went on, "Now that you've shown him how excited you are to watch your bride-to-be take on a big black cock, take his clothes off so we can get started with your lesson."

He stood up--towering probably eight inches above me. My hands brushed over his firm, well-developed pecs as I unbuttoned his shirt, and when I pulled it open, there was a sprinkling of wiry black hair between them. I pulled his shirt up out of his slacks, held it while he extracted his arms, and then I folded it and set it on the dresser. I looked at the broad expanse of his back and his narrow, athletic waist, and my naked boner throbbed and oozed some precum. Harry was a frigging black Adonis!

I undid his belt then the button of his pants, and pulled down his fly. I opened his slacks and slid them off his hips and over his firm, round ass. He was wearing black, tight, short-leg briefs, similar to the ones I had just taken off, and when I slid his pants to the floor I was bent over and looking at the biggest bulge in a pair of shorts I had ever seen! It stretched down one leg, coming within an inch of its tip poking out into view... and I was pretty sure the damned thing wasn't fully hard yet!

I went into a crouch so my head was level with his groin, and I reached up and slid my fingers into the elastic waistband of his shorts. I began pulling down, stretching the waistband over his bubble-butt first, leaving the front high, and saving the best for last.

As the base of his dick came into view I saw that he was cleanly "manscaped," which made the transition from his flat lower-stomach to his thick cock-root even more pronounced. I kept pulling his shorts down, down, down, slowly exposing inch after inch of the first BBC I had ever been close to. When I finally got low enough, his cock jumped free of the last inch or so and sprung out almost hitting me in the face. It hung at about a forty-five-degree angle and rose and fell a bit as he breathed.

It was enormous! Easily the biggest cock I had ever seen in real life and rivaling many I'd seen in porn movies. I was even more sure now that it wasn't even fully erect yet! Apparently, Mandy picked up on the same thing.

"Take him in your mouth and make sure he's good and hard for me," Mandy commanded me. "I want to feel the fullness of that big black cock stretching my pussy like you could only dream about doing!"

His dick was circumcised and his cock-head was about the same diameter as his shaft --unlike mine, which is a mushroom atop my boner. It transitioned to his shaft with a small-ish ridge, then the shaft expanded quickly to its fat, consistent girth, all the way to its root. A couple of heavy veins twisted their way along its length.

I was able to get both of my hands on his shaft and I lifted it up and pressed my pursed lips against its head. I went forward until I felt his ridge under my lips and then swirled my tongue over his knob. I love to tip-suck a fat, squishy cock-head, and in squishiness, Harry's was a bit of a let-down, but it sure made up for it in size! Even his pee-hole was huge and I wiggled the tip of my tongue farther into it than I'd ever done before.

After I'd enjoyed his knob for a while I leaned in farther and let his monster force my mouth open wider than any cock I'd ever sucked. When I had it completely filling my mouth, I considered trying to force it down my throat, but I wasn't sure it would physically fit without causing some permanent damage, so I started bobbing and giving him a wet, sucking blowjob with my tongue pressed firmly against his knob-cleft. As I bobbed, I began running one hand up and down his shaft while I fondled his balls with the other. They were easily the largest I'd ever had in my hand!

As I bobbed, stroked, and fondled, Harry looked at Mandy, and said, "Oh, man! Your hubby-to-be is good at that! This ain't the first cock you've made him suck on, is it?"

"No," she said. "Just his first

black

cock. And I'm sure the biggest."

As I sucked and lapped the first few inches of his enormous boner, it occurred to me that he must get frustrated by not being able to get more of his dick into anyone's mouth. It was hard for me to imagine even the most experienced porn star being able to get that monster down their throat. So, I was determined to give him the best limited-depth blowjob I could.

Judging by his hums and the occasional "Oh, yeah!" I think I was doing a pretty good job. Then he put his big hands on the sides of my head and gradually stopped me from bobbing while at the same time, he began rocking his hips to fuck my mouth. In time with his fucks, I was stroking his shaft and I continued to massage his balls.

He was big enough and strong enough--and his dick was stiff enough--that if he'd wanted to, he could have held my head still and driven his stiff cock right through the back of my skull, I think. But he was a surprisingly gentle giant and fucked my mouth in a manner that gave me as much pleasure as it appeared to give him.

As my jaw began to ache from being held open so wide, he said to Mandy, "You okay if I blow my load in his mouth? I guarantee I can get hard again for round two."

She bent down next to my ear, and taunted, "You wouldn't mind that would you, sweetie? You don't mind if he fills your mouth with his hot, thick cum, do you?"

Dutifully, I answered, "Mm, mm," around a mouthful of cock. In my head, I was saying, "

Oh, fuck! Please!

"

She went on, "And you'll get him hard again so he can fuck me while you watch, won't you?"

This time I mumbled "Mm, hmm," in the positive. I could only hope that his big dick would go at least somewhat soft so I could stuff more of it into my mouth. I think I might have mentioned that I love a mouthful of squishy cock!

She straightened up, kissed Harry on his full lips, and then told him, "Go ahead and fill his mouth with your seed. Show him what fresh cum from a black cock tastes like."

He had never really stopped fucking my mouth during all this, but now he picked up the pace as he held my head and rocked his hips. His strokes grew a bit deeper, with his pointy knob poking into the entrance to my throat. If he had tried to jab his monster down my throat, I would have tried like hell to take it, but he was gentlemanly enough not to force himself on me. Instead, I ended up with the completely new experience of getting my throat tip-fucked, and I loved it!

As one of my hands flew up and down his shaft and the other massaged his big balls, I heard him start to groan and he picked up his fuck-pace even more. Then he pulled back until just the head of his cock was between my lips and he grunted as I felt his ball-sack contract.

With my fingers wrapped around his cock I felt his urethra expand as his load of cum traveled its length to escape into my sucking mouth. I think he must have been holding and building this load for a long time because the first thing to hit my tongue was a coagulated glob of cum. I would love to have taken that little wad of sperm and rolled it around in my mouth all by itself, but the powerful stream of hot jism that followed right behind it pushed it off my tongue and it was lost in the growing puddle of cum that was quickly filling my mouth.

After his long first-spurt, he replaced my hand on his cock and began to jerk off. I heard Mandy tell me, "Open your mouth! I want to see his hot splooge filling you up! And don't swallow until he's done!"

Happily, I did as I was told and felt squirt after squirt of cum hit my tongue until his pooled jism was dribbling from the corners of my mouth. Finally, his grunts and slower pulls on his cock told me he was nearing the end of his orgasm, and he finished off by rubbing his cock-head across both of my lips, smearing the last oozes of his cum across them.

Then, he surprised both Mandy and me by telling me, "Don't swallow!" and pulling me up to my feet with his big hands on both sides of my head. Then he pressed his full lips against mine and pushed his tongue between them. He didn't have to explain what he wanted and I opened my mouth with his and we swapped his fresh cum back and forth before we each swallowed our share.

I'm not much into kissing guys; it just doesn't turn me on the way that kissing a girl does for some reason. But swapping a mouthful of hot cum is different, and I'll do that all day long.

When we swallowed, he reached over and pulled Mandy in and we shared a steaming, cum-smeared three-way kiss with tongues going in all directions. When he broke the kiss, he held both of us close, and said, "You know, I think the two of you are trying to bullshit me. You ain't really what you say you are, are you?"

We were both shocked. How could he have figured out we weren't husband- and wife-to-be but brother and sister? And was that going to kill everything? Was that too perverted, too weird for him?

Then he went on and relieved our anxiety. "Soon-to-be-hubby here is no dominated cuckold; he doesn't need to be

forced

to suck cock, does he? He's bi all right but he's no cuck. Am I right? The sub/dom thing is just a role-playing thing for you two, isn't it?"

Mandy and I looked at each other but before we could reply, he went on, "Hey, I'm okay with it if that's what turns you guys on; I can play along. But don't think you have to do it on my account. I'm more than happy to just have a straight-up bisexual threesome with you. I've been looking a long time to find a couple that I could be comfortable around and really open up with. Nobody in my regular life knows I'm bi and couldn't accept it if they did, so it's not something I've been able to explore easily or freely."

"You're very perceptive, Harry, and you're right," Mandy said. "The cuckold thing is an act we like to play out. I've always been a bossy bitch, so domination just runs in my blood and it turns me on to be in control. And I've found that a lot of guys seem to get turned on watching me dominate my hubby-to-be and

forcing

him to give them a blowjob or eat their cum out of my fresh-fucked pussy."

I added, "And you're right about me; I'm as bi as they come. And I love every minute of playing the subservient cuckold. It's funny that some guys we've played our game with who aren't bi wouldn't accept a blowjob if I just asked them if I could suck their dick, but when Mandy

forces

me to do it, they can't wait to fuck my mouth.

"It goes about fifty-fifty with them," I went on, "whether they think blowing their load in my mouth or shooting their splooge all over my face is more humiliating for me. I prefer in my mouth, of course, because I get to taste a lot more of their cum, but either way, I always make a face like what I'm being forced to endure is the most disgusting thing in the world." I chuckled, and added, "They seem to like that."

He nodded in understanding, and then, looking at Mandy, he said, "Nobody's ever bossed me around in the bedroom but I think I'd like to give that a try. Go ahead, Miss Bossy-Bride, tell me what to do."

She broke into a wide, almost evil smile, and replied, "Oh, with pleasure!"

He looked at me, and joked, "Uh oh! What Have I gotten myself into?"

"Maybe the best night of sex you've had in a long time," I answered.

"If it continues like it's started," he said, "you're right about

that

!"

"Put your hands behind your back," she told Harry as she stepped over, picked up my pants, and slid the belt from its loops. She went behind him and tied it around his wrists in what was mostly a symbolic knot. A belt is a terrible thing to restrain anyone with, and he could easily have gotten free if he wanted to. He obviously didn't.

Then, Mandy said to me as she pushed me down to my knees, "Get him hard again. I seem to remember a promise of a round-two and my pussy is aching to feel that black monster spreading it open."

Harry's dick had softened a good deal after blowing his load in my mouth, but it hadn't shrunken completely and the damned thing was still bigger than a lot of guys with a full hard-on.

I took it in my mouth and rocked and twisted my head to get as much in as I could while it was still flexible. I jammed his knob into one cheek and forced his shaft to bend and stuffed it crossways into the other while I flicked my tongue over it. That contorted-cock mouthful lasted only a handful of seconds before his blood began to refill his cock and straighten it back out.
